DividendDistributor.distributeDividend(address) (#242-252) ignores return value by BUSD.transfer(shareholder,amount) (#247)
DividendDistributor.clearStuckRewards(address) (#278-280) ignores return value by BUSD.transfer(_address,BUSD.balanceOf(address(this))) (#279)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

PurePonzi.takeFee(address,uint256) (#427-436) performs a multiplication on the result of a division:
-feeAmount = amount.mul(getTotalFee()).div(feeDenominator) (#428)
-burnAmount = feeAmount.mul(burnFee).div(totalFee) (#429)
Consider ordering multiplication before division.

PurePonzi.swapBack().e (#534) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Variable 'PurePonzi.swapBack().e (#534)' in PurePonzi.swapBack() (#497-539) potentially used before declaration: SwapBackFailed(string(abi.encodePacked(SwapBack failed with error ,e))) (#535)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

DividendDistributor.shouldDistribute(address) (#233-236) uses timestamp for comparisons
Dangerous comparisons:
- shareholderClaims[shareholder] + minPeriod < block.timestamp && getUnpaidEarnings(shareholder) > minDistribution (#234-235)
Avoid relying on block.timestamp.

DividendDistributor.process(uint256) (#213-231) has costly operations inside a loop:

- totalDistributed = totalDistributed.add(amount) (#246)
DividendDistributor.process(uint256) (#213-231) has costly operations inside a loop:

PurePonzi.totalFee (#295) is set pre-construction with a non-constant function or state variable:
- liquidityFee + reflectionFee + marketingFee + burnFee
PurePonzi._maxHold (#296) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 100
PurePonzi.swapThreshold (#318) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 2000
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

Pragma version^0.8.11 (#14) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.11 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in PurePonzi.swapBack() (#497-539):

Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
